Simple (theoretically at least) Issue regarding splitting songs into 3 columns.

I'm helping out on a server for people who get triggered by loud noises and fireworks for the fourth of July, and one of the things I need to do is put all of these songs into a spreadsheet in three columns: Song, Author, and Album. I have a list of songs that's listed alphabetically into this format:

Life Is A Highway - Tom Cochrane - Mad Mad World (Deluxe)

aka

Song - Author - Album

and I want to (either using excel or sheets) split it into three seperate columns without having to do it manually in either sheets or excel. Thanks so much!
